DALY CITY — A city police officer who allegedly used his gun in an effort to extract information from a man during an auto-theft investigation could be charged with assault under color of authority.

The officer, identified as Alfonso Esqueda III, surrendered to authorities at the San Mateo County jail Friday after a

$100,000 warrant was issued for his arrest, police said. He was released on bond.

According to a police statement, Esqueda, 32, contacted a 20-year-old Daly City man July 25 during an auto-theft investigation and “placed his gun at the victim’s head” in order to elicit the information he was seeking. Esqueda later drove the man to another location to look for stolen vehicles, later releasing him unharmed.

The incident was observed by a second officer who reported it to his superiors, triggering the investigation, police said. Both the Police Department and the District Attorney’s Office are conducting the probe.

Esqueda has been with the Daly City Police Department since September of last year. He came to Daly City from the Long Beach Police Department.

He’s due to appear in court Sept. 8 for arraignment on several charges, including brandishing a weapon, assault with an automatic weapon, and assault under color of authority.

In the meantime, he is on paid administrative leave, according to the police statement.
